Hi everyone! I recently took a trip on Southwest from Phoenix to San Jose. An interesting thing happened on the take-off out of San Jose. There was the normal power reduction at about 1000 feet, but then another unexpected and pretty large reduction about a minute later. The engines powered up again after about 2 minutes and things went on as usual. I never felt uneasy or in danger in any way, but I'm a little confused about that second power reduction. Things were nice and smooth, no clouds... Does anybody know what happened? Maybe noise abatement procedures?

If you took off to the north the departure procedure includes a level-off until you complete the turn southbound and clear the arrival corridors for OAK and SFO. That level-off is often removed by ATC if there is no conflicting traffic. If you took off to the south there is no published reason for a second power reduction... perhaps ATC deconflicting your acft with other traffic?
